750 K1 Valves cover
« on: October 06, 2013, 08:50:03 PM »
Roughly 2 weeks ago my valve cover started to seep oil on the left side... nowhere else.... I'm pretty sure I am done riding for the season...Is it possible to simply loosen all screws on the valves cover and retighten to see if the seepage subsides? Or should I attempt to tighten the one side?

Check if they are loose' only snug them a bit. Really cranking it up...just bends parts.

I've never seen a bent valve cover, but I guess it's possible. I like plan A, loosen all screws and re-tighten them evenly, and see if that seals it. The oil should have swelled the gasket slightly, so that might actually help it seal. Cheers, Terry. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

I think I'd be more worried about stripping the threads out of the head Frank, especially if the screws have been replaced with stainless socket heads. ;D

If youcan get at them 2 under the breather cover loose, you could lift cover and apply sealant.
